BulletSim: Convert BSCharacter to use common BSPhysObject code and variables.
Fix avatar height calculation to properly account for the capsule ends. Rearrange some locking in TerrainManager to eliminate possible race conditions. Move DetailLog() definition into common BSPhysObject class. Some variable renaming to make usage clearer (refactor.rename makes this so easy).connector_plugin
